integrate 1 over y and z first, i.e. integrate over the circle x = 8x^2 + 8y^2, where x is fixed. can you do this? then integrate these elements (which are functions of x) * x over x between 0 and 8...

to make thing simpler, use cylindrical coordinates.

I know how to integrate but I don't know how to setup the limits of integrations
